Vibration-damping seat

[0021] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0022] Such as figure 1 with figure 2 As shown, the damping seat includes a lower support 1, an upper support 2 and a backrest 3 connected to the upper support 2. The connection between the backrest 3 and the upper support 2 is provided with an adjuster 10 capable of adjusting the elevation angle of the backrest 3. As the body of the user is different, the required elevation angle of the backrest 3 is different, and the adjuster 10 can adjust the elevation angle of the backrest 3 according to the actual needs of the user. A spring 6 is provided between the middle of the upper support 2 and the lower support 1, and a number of dampers 5 are symmetrically distributed on the front and rear sides between the upper support 2 and the lower support 1. In this embodiment, the number of dampers 5 is two, but as another solution, it may be more than two. The most important impact of a car comes from acceleration or sudden braking. With dampers 5 installed on the front and rear sides of the seat, the vibration caused by acceleration or sudden braking can be reduced to the greatest extent. Two cross members 4 are respectively provided on the left and right sides between the upper support 2 and the lower support 1. The cross member 4 includes two hinged sliding rods in the middle. The two ends of the sliding rods are respectively arranged on the upper support 2 and the lower support. In the sliding grooves 11 on the front and rear sides of the support 1.

[0023] Between the spring 6 and the upper support 2 and the lower support 1 are also provided an upper positioning member 7 and a lower positioning member 8 capable of fixing the spring 6. The upper positioning member 7 and the lower positioning member 8 are respectively connected to the upper support 2 and the lower support Block 1 is firmly connected. The upper positioning member 7 and the lower positioning member 8 prevent the spring 6 from moving during use and ensure the accuracy of the elastic force point of the spring 6. A rubber pad 9 is also provided between the spring 6 and the upper positioning member 7 and the lower positioning member 8. The rubber pad 9 can play a certain role in increasing the force area.

[0024] Such as image 3 As shown, the adjuster 10 includes a fixing frame 17 fixed on the upper support 2 and a gear 12 fixed on the backrest 3. The gear 12 passes through the fixing frame 17, and the fixing frame 17 is provided with a thimble 13 and a guide Block 15, the thimble 13 is provided with handles 16 on both sides, the end of the thimble 13 is stuck between the two teeth of the gear 12, the thimble 13 is slidably connected with the guide block 15 and can be separated from the gear 12 when the thimble 13 slides along the guide block 15, A return spring 14 capable of resetting the thimble 13 is arranged between the tail of the thimble 13 and the fixing frame 17. When the elevation angle of the backrest 3 needs to be adjusted, manually pull the handle 16 to make the thimble 13 work along the guide block 15 to overcome the return spring 14, and the thimble 13 and the gear 12 are separated. At this time, the angle of the backrest 3 can be manually adjusted. When the thimble 13 is opened, the return spring 14 pushes the thimble 13 to be caught between the two teeth of the gear 12 to fix the gear 12 circumferentially. Because the gear 12 and the backrest 3 are fixedly connected, the backrest 3 and the upper support 2 are locked at this time.

[0025] The main working principle of this device is as follows: the car body will vibrate when the road is bumpy and the speed changes drastically. The vibration is transmitted to the lower support 1 of the seat through various parts on the car body, and the lower support 1 is passed through springs. 6. The damper 5 and the cross member 4 are transferred to the upper support 2. In this process, the two ends of the two sliding rods of the cross member 4 slide in the chute 11 and change the distance between the upper support 2 and the lower support 1. The spring 6 converts the vibration of large energy into multiple vibrations. For small energy vibration, the damper 5 reduces the number of small energy vibrations and eliminates vibration. When the user sits on the upper support 2 and the vibration on the vehicle body is transmitted to the user, most of the vibration has been eliminated, which improves the comfort of the user. The two dampers 5 of the device are symmetrically distributed on the front and rear sides between the upper support 2 and the lower support 1, and the vibration damping seat can be well cushioned in both front and rear directions, and vibration can be greatly eliminated.
